Question

vii) If the ratio of four angles of a quadrilateral is 3:4:5:6​

Answer 1

Answer:

let angle be x

then all four angle are 3x, 4x, 5x, 6x

3x+4x+5x+6x=360

(sum of all angle of quadrilateral is =360)

18x=360

x=360/18

x=20

angle 1 = 3x=3×20=60

angle 2=4x=4×20=80

angle 3= 5x=5×20=100

angle 4=6×20=120

Answer 2

THE ANGLES ARE 60,80,100,120
